Allow Private IPs

[hideki-a]

Thank you for creating this container.

I would like to check HTML on a non-public address.
Can you Edit validator.conf and change Allow Private IPs = no to Allow Private IPs = yes?

Thank you for your cooperation.

Thanks for the comment @hideki-a - seems like a worthwhile addition. Of course the Docker instance will still need to be able to resolve the DNS entry given, by default Docker uses Google's DNS servers (from memory) - but giving an IP address to validate I guess would still function.

Leave it with me - will implement when I get a moment.
